Default LED Flood Lights

I have two 50 watt sealed halogen flood lights on my t-top that pop the circuit breaker after about 5 minutes of use. Anyone know if they have an LED type light out there? I figured I could surf the web, but ya'll probably know what I'll need already.

Time out - do you really want LED's or are you looking to fix your problem? 2 - 50W @ 12 V should be about 8-9 amps. What is the rating of the C.B.? If it's 10 or more it should be correct for the application. Check the current draw on the circuit with an ampmeter. If it's what I say and the breaker still pops (and is rated over 10A), it's bad. If current draw is high, you may have a bad bulb. Bad breaker is more likely. Don't think you'd ever get the kind of output from LED's you get from a 50W Halogen flood.

Follow up - if you have another similarly sized breaker on the boat you could switch the circuit over to that one to confirm the original one is bad.

LEDs cannot produce the light output of halogen bulbs. When you see LED trailer lights or navigation lights these are actually "arrays" of LEDs (several LEDs in the same housing). It would take hundreds of LEDs to approach the light output of a 50 watt halogen bulb.

As for fixing your problem, did the lights come on the boat from the factory or did you or someone else install them? There's a good chance that the lights are overloading the circuit and the breaker is doing its job by shutting the circuit down. The fact that they work for five minutes or so points to this. Whatever you do, don't substitute a larger breaker.

Check the breaker by swapping it out with a "known good one" as suggested above. If this doesn't correct the problem you're going to need to determine the current draw, check to see that the wires running to and from the lamps are large enough for this current, and that the breaker is the appropriate size to protect those wires. You may find that you need to rewire them with a larger wire size and then increase the breaker rating.

In answer to your question, check out www.superbrightleds.com . I just bought some replacements from them to change my existing white lighting to led red. No floodlights per say, but you may find something that fits your needs.

LED “floodlights” are available albeit expensive but they are 110 volt. I just completed an energy management plan for a client and replaced 150 regular floodlights with LED’s. Payback from energy savings is estimated at 14 months. Not bad for just switching bulbs, but the higher output bulbs are not yet available in 12 volt……….. Stay tuned, their on the way……………………..

Never officially checked the amp draw or beaker. Had to do some quick work before we went fishing. I separated the two lights on different switches and they seem to work fine. I'll find the culprit during the week.

On the LED subject, I have a 5 LED bulb flashlight that puts out a decent amount of light. I would have to say if you put 30-40-50 led's in a unit it would throw out plenty of light. I'm not sure what the amp draw would be on something like that, so I might be back in the same boat.

Have you thought about a fluorescent light? They put out a ton of light and very little battery drain.

LEDs draw about a tenth the current of an incandescent lamp of the same light output but they are very limited in the amount of light a single LED can produce.

Florescent lights are more efficient than incandescent but they can't really be focused like a single source can.

Lots of good information on LEDs at the website posted above.

I'm not sure of the reason, but fluorescent lights on boats make me nauseous.

rwidman, try Wiley's new Google thingy and use LED Floodlights as the search word. PS: it's the Enlux link........
